I started to do the same with array methods, but before I spend too much time on it, I'd like to be sure I'm doing the right thing.
1. In add_newdocs.py, add
from numpy.core import ndarray
2. then add an entry for each method, eg
add_docstring(ndarray.var,
"""a.var(axis=None, dtype=None)
Return the variance, a measure of the spread of a distribution.
The variance is the average of the squared deviations from the mean,
i.e. var = mean((x - x.mean())**2).
See also: std
""")
3. in arraymethods.c,
delete static char doc_var[] = ...
remove doc_var in
{"var", (PyCFunction)array_variance,
METH_VARARGS|METH_KEYWORDS, doc_var},
